在此基础上，分析了热成因煤层气与次生生物成因煤层气的气源潜力，对研究区煤层气勘探有实际意义。 - New achievements having been obtained in this field show that co2 participating in karst process in the epikarst dynamic system mainly comes from soil air co2 created by the organic carbon , in other words , although karst is a kind of biochemistric action in nature , distribution and transmit and cycle of carbon rely on changes of soil organic carbon . soil organic carbon is the greatest carbon storeroom . soil respiration emission of co2 is the most important passing entrance in carbon cycle of epikarst ecosystem
已有的研究表明：参与岩溶作用的co _ 2多数属于土壤中生物成因，也就是说，尽管岩溶作用是一种自然界无机化学作用，但碳的分布与转移及循环仍以生物活动为纽带的土壤碳积累为转化中心，土壤有机碳构成系统最大的碳库，土壤呼吸碳表现为该系统中最重要的碳流通途径，因此进行土壤co _ 2浓度观测及其影响因子分析是研究表层带岩溶生态系统运行机制和全球碳循环的首要条件。
